KR970014207A - Character Display Control Device of Television Using Teletext Characters (APPARATUS FOR CONTROLLING CHARACTER DISPLAY BY USING TELETEXT CHARACTER DATA IN TELEVISION) - Google Patents

Abstract

The present invention stores various character or figure data included in service data of teletext information superimposed on a television broadcasting signal and can be utilized as font data for screen display of function items for overall functional operation of a television. Provided is a character display control apparatus for television using teletext characters.

Accordingly, according to the present invention, the video signal of the television broadcast signal amplified by the video amplifier 2 is processed by the video signal processing module 4 to play the video on the screen of the CRT 8 through the video output unit 6. For television; Teletext processing means (10, 12, 14) for extracting and decoding teletext information included in the video signal, and the service data of the decoded teletext information through the teletext processing means (10, 12, 14) A memory interface 16 for interfacing the screen data with the font data, and memory means 18 for storing the font data of the teletext information through the memory interface 16, and the overall functional operation of the television. A function setting unit 20 for setting a setting item for a key, and a font is set for a setting item for a function operation by key setting of the function setting unit 20, and the memory means corresponding to the set font ( The microcomputer 22 and the microcomputer 22 which control the display items to be displayed on the screen through the font data according to the teletext information by searching the font data of FIG. 18). From the control register 24 and the memory unit 18 read through the memory interface 16 to search for font data to be searched and to control data display of the font data according to the search result. Characterized in that it comprises a display character processing unit 26 for signal processing to convert the font data into an RGB color signal in the form of an analog signal to be displayed on the screen.
